NVE has taken low power to unprecedented levels with the AAT009-10E Ultra-Ultra-Low
Power Tunneling Magnetoresistance (TMR) Angle Sensor.
The New AAT009-10E Ultra-Ultra-Low
Power Angle Sensor
AAT sensors measure angular position based on rotating magnetic fields. Typical
applications include rotary encoders, and motor shaft position sensors, and Internet-of-Things
end nodes.
Key AAT009 features include:
• 6 MΩ typical device resistance for ultralow power
consumption
• 0.5° maximum angular measurement error (fixed bias)
• 200 mV/V peak-to-peak output signals
• Wide magnet airgap tolerance
• Sine and cosine outputs for direction detection
• Ultraminiature 2.5 mm x 2.5 mm x 0.8 mm
TDFN6
The AAT009 can run years on a single button cell. The sensors detect and maintain
absolute position information, and immediately power up in the correct position
after power is restored.
There are now three AAT-Series sensors:
